hey guys, my car when turn on it iddles very good like around 7-800rpm but then a few seconds after, the iddle starts to increase slowly up to 1500rpm...any of you guys know what might be wrong with it? i'd tried switching out the map sensor, replace a different throttle bodie and still doesnt work. at first my gas peddle kinda stuck everytime i let go of the gas..so i adjust the throttle screw and losten it alittle and it that happen...

any idea?
